Requisite user qualification:
ELECTRICAL SPECIALIST
Electrical connections may only be performed by an
ELECTRICAL SPECIALIST as defined in the chapter
User qualification.
Spring contacts can be opened with a simple screwdriver in order to
connect a cable:
1.
Insert a matching screwdriver into the aperture above the
terminal as far as possible.
2.
Gently pull up on the screwdriver's handle. This lever effect
pushes the screwdriver's tip down, thereby opening the spring
contact.
3.
Once the spring contact is open, insert the cable into the
terminal.
4.
Pull out the screwdriver.
5.
Check that the cable is sitting securely by pulling on it lightly.
IMPORTANT NOTICE!
Force application on connection terminals
To avoid damage, do not apply any excessive force on
the terminal using the screwdriver.
